JAMES yw. WELSH, DEPEOVIDENOE, `RHODE ISLAND, lAssrofivon trocnauson ANDLOMB QPTICAL COMPANY, OE ROCHESTER, NEW YORK, vA CORPORATION 0FSPECTACLE ATEMPLE.AND METHOD OE MAKING vTHE SAME.

Application filed January s2, 1924. Serial '-No."687,697.

VThe present invention relates to ophthalmic mountings and methods ofmaking the Asameand more particularly to ymetal-reinforced, non-metallicspectacle't'emples.

In some types of temples ofthe above- --described character, a metalreinforcing rod,

.ing that the hidden reinforcing rod, whichA could otherwisebeconstituted ofbase metal,

must be of the samemore valuableimetal y asthe moreconspicuous'hiiggeplate. In the more Lusual case, it is desired tohavethe reinforcing rod ofawlight-weight metal, like aluminum,'and thismetal wouldfnot have the strength required `of a hingeplate.

It is accordingly anobjeot of thepresent u Vplate 10 to lie fiush .withthe'face 5 of the invention to .provide aspectacle 'temple `having alreinforcing rod and a hingey element soldered or otherwise securedtogether, yand that mayl readily bev mounted inf place in the iTanon-metallic material.

Other objects of the invention will4 appear from the followingdescription, taken in "connection with the accompanying drawings, in'which Fig. 1 is a plan of a spectacle temple constructed according to apreferred einbodiment of the oresent invention; Fig. 2 is an elevationof t e same: Fig. 3 is a fragmentary elevation of a non-metallic tube,and Fig. 4 is an elevation of a combined reinforcimg` rod and hingeplate adapted to be united to form a temple such as is illustrated inFigs. 1 and 2; Fig. 5 is a. section taken upon the line 5-5 of Fig. 3;Fig. 6 isv a fragmentary elevation of the combined reinforcing rod andhinge plateshownin Fig. 4; and Fig. 7 is an elevation corresponding toFig. 2 of a modification.

The preferred temple of the present invent-ion comprises a non-metallicmember,

shown as a seamless tube '2, provided at its forward end'withahinge-plate-receiving recess 4, yin one face 5, that communicateswith'the bore' of the tube. A reinforcing 'rod 8, to' which aliingeplate 10is soldered or otherwlse'secured, isy inserted through ,the recessL.Land intothe bore 6 of thejt-ube 2, the hinge plate lO'being seated inthe recess 4L. A rivet oi' screw 12 may be employed vto securevtliehi'nge plate 10 tothe `tube 2. "The rearendl?) ris then upset,` asVshown at ,'15, `and the upset,portion'becomes seated yin a Vrecess 17providedin the extreme rearend ofthetubeQ: `The rear portion ofv,thetube, with the reinforcing rod therein, Vmay be bent intoear-liookshape, asin the oase of` the cable temple 'shown inFigs 1 andQ, into the'shape of a. skull temple, as shown yin Fig.

7or in any other desired temple shape.

`The forward portionof the reinforcing .rod is shownat 13 as square rorpolygonal in cross section. This construction. provides a flatface 14 ofthe reinforcing rod to contact-with a fiatface .16 .of the hinge plate,

ensuringa secure union when the reinforcing rodand the vhingep-late aresoldered or `otherwise secured together. rlhe :extreme forward end ofthereinforcingro'diis offset at'18,=which enableszthe body of thereinforcing rod' to lie in the `bore 6,V and the 'hinge tuberQfasisillustrated more particularly solvent, such as acetone. In the case of aCable temple, however, the rear portion 2O of the reinforcing rod shouldbe round, and preferably of the cable type employed in metal cabletemples; and the corresponding portion of the non-metallic materialmounted on the round portion of the reinforcing rod may be of anydesir-ed form, suclias a continuation of the tube, but cut helieally.

Other modifications also will readily occur y Vto persons skilled in theart, and all such are intended to be included within the spirit andscope ofthe appended claims.

l/Vhat is claimed is:

1. A spectacle temple comprising a nonmetallic seamless tube having arecess communicating with the bore of the tube, and

a reinforcing rod in the bore having a hinge plate secured theretoseated in the recess.

2. A spectacle temple comprising a nonv metallic tube having a recesscommunicating With the bore of the tube, and a reinforcing rod in thebore having ahinge plate seated in the recess, the reinforcing rod andthe hinge plate having contacting flat faces along Which the reinforcingrod and the hinge plate are secured together.

8. A spectacle temple comprising a nonmetallic tube having a recess inone face con'imunicating With the bore of the` tube,

Vand a reinforcing rod in the bore having ble and of round crosssection, the temple having a coil of non-metallic material mounted onthe round portion of the rod.

5. A spectacle temple comprising a nonmetallic tube having a recess inone face communicating With the bore of the tube, and a reinforcing rodin the bore having a. hinge plate secured thereto mounted inthe recessthrough the said face of the tube.

6. A spectacle temple comprising a nonmetallic, seamless tube having arecess in one face communicating with the bore of the tube, and areinforcing rod in the bore having a hinge plate seated in the recessflush with the said face of the tube, the reinforcing rod and the hingeplate having lcontacting flat faces along Which the reinforcing rod andthe hinge plate aresecured together. v

7. A spectacle temple comprising a nonmetallic tube having a recesscinone face communicating with the bore of the tube, and a reinforcing rodin the bore having a hinge plate secured thereto lying in the recessflush With the said face of the tube.

8. lA spectacle temple comprising anonmetallic, seamless tube having arecess in one face communicating with the bore of the tube, and areinforcing rod in the Ybore having a hinge plate secured thereto seatedin the recess flush With the said face ofthe tube, a portion of the rodbeing flexible, and the temple having a coil of'non-metallic materialmounted on the flexible portion of the rod.

9. A spectacle temple comprising a nonnietal member, and a reinforcingrod in the non-metal member having `a separate hinge plate securedthereto, the hingeplate being disposed in the non-metal member andhaving a knuckle projecting beyond the nonrnetal member.

10. A spectacle templev comprising a nonmetallic tube having aVlongitudinally disposed bore, andVV a metal hinge element mounted on thetube, the hinge element having an integral rod extension oifset from thehinge element and mounted in the vlongitudinally disposed bore of thetube.

l'l. A spectacle temple comprising a non metallicy tube having a recesscommunicating with the bore of the tube, and a metal hinge plate mountedinthe recess, the hinge plate having an integral rodl extension mountedin the bore of the tube.

f l2. A spectacle temple comprising a nonmetallic member, a metal hingeelement mountedon the non-metallic member, and a member integrallysecured to the hinge element in offset relation thereto, the memberbeing secured to the non-metallic member to protect the portion of thenon-'metallic member near the hinge element. from the strains caused byflexing the temple. lntestimony whereof, I have hereunto subscribed myname this 19th day of J anuary, 1924.
